21GRAMS· New York, New York, United States
21GRAMS is the advertising and education arm of Real Chemistry. Ranked the #2 health agency in the world by Cannes Lions. More than a name, 21GRAMS is the philosophy that guides everything we do. Inspired by the “21 Grams Experiment” of 1907, which tried to prove the existence of a soul – we believe great work connects with the human spirit. So we get to know our audiences better than anyone (through the ancient art of human interaction and Real Chemistry’s industry-leading data and analytics) and find the 21 grams that makes people tick. Our goal? Make advertising less of an interruption – and more worth people’s time, attention, and action – because it actually “gets” them. Creatively, our mantra is “medicine should be more inspiring than sneakers”. We aren’t here just to do the best work in our industry, but the most inventive work period. That ability is heightened, as part of Real Chemistry. Interacting and combining unalike disciplines, talents, and technologies (across Clinical, Commercial, and Corporate) to create new answers to modern health’s biggest challenges.
